Thanks Mark. Indeed your recommended action works when I add shape file and left-click to see attributes.
However, when I add "GIS service", the objects are displayed on Map as expected. But in this situation, left-click does not show me properties.The cursor remains as "hand" icon, presumably for pan action. Then I did some troubleshooting, checked property. I had to enable popup there and now I get to see properties popup. So, we can treat this subject as closed.
